Sandy Springs Police find three dead from gunshot wounds (UPDATED)

Police are investigating the shooting death of three people at a home in Sandy Springs on Brandon Ridge Drive. Investigators say the victims are an elderly woman and her two adult children.

The incident is still under investigation and police aren’t offering a definite motive, but they also aren’t ruling out a possible murder-suicide.

The shooting shocked residents in the quiet neighborhood.

“It’s actually sad,” said neighbor Jim Terrell. “It’s surreal.”

Investigators collected evidence inside the home – they are treating the house as a crime scene.

“We found a weapon in the house, we haven’t concluded that was the weapon that was used those tests will be done, but we know the weapon was found in close proximity one of the victims,” said Steve Rose from the Sandy Springs Police Department.

Authorities said 89-year-old Edith Renner and her daughter, 49-year-old Suzanne Renner, lived together at the home where the shooting occurred. Police also found Suzanne Renner’s brother, 45-year-old Charles Renner deceased inside the house.

“I heard a bam,” said Terrell. “Just one time, just a distinctive bam.”

Officers discovered the bodies after a friend of one of the victims called police to make a welfare check because one of the victims never showed up to work on Wednesday. That’s when police and neighbors learned Edith Renner and her children were dead.

“My wife would take her shopping,” said neighbor Phil Kranz. “She was just the sweetest, kindest, gentlest woman you’d ever want to meet.”
